Part Number : E27/60SMDWW

This E27 LED bulb features 60 individual high quality 5050 SMD LEDs that emit a
light output of 380Lm. They're intelligently designed to considerably reduce energy
consumption by up to 90% and are available in both Warm and Cool white options. When
ordering these particular lamps you will see they are only available in a dimmable
option. This means they are fully compatible with both dimmable and non-dimmable
applications. Using only 4.5 watts of power these are by far our most energy efficient
bulbs available and equivalent in brightness to a 40 watt bulb.

These E27 bulbs feature a massive 120-degree beam angle; designed to output the
widest beam angle available of any SMD bulb on the market today. These bulbs will
install into any Edison Screw (ES) socket with an input voltage of 240V and is designed
for any domestic, commercial or retail installations. They use only 10% of the energy
when compared to the older style bulbs, thereby offering significant savings that
consumers simply cannot ignore.

Lasting 50,000 hours compared to a halogen lamp which last 2000 hours, LED bulbs
usually pay for themselves within six months of installation. Homeowners and businesses
can now go years without the hassle of having to change bulbs. These LED equivalents
feature shock and vibration resistant technology, there is no filament to ever burnout
so they run considerably cooler than standard filament bulbs.

Main Features:

• 60 individual high quality SMD chips, 120 degree beam angle
• Cost Effective Energy Savings within 6 months of installation
• Spiral alloy housing - great for dispersing heat
• 30-year Average Lifespan (6-year Lifespan when left on 24/7)
• Consume 10% of the energy used by traditional light bulbs
• No start-up delay or flickering, normal brightness when electrified
• LED bulbs do not contain a filament that can easily be damaged
• Environmentally Friendly - LED bulbs contain no Glass or Mercury.

LED lamp energy saving comparison

Lamp colour ( Kelvins )

The colour of a lamp is defined as a measurement called kelvins. A standard GLS
light bulb in your house would be 2,700 kelvins which is in the warm colour spectrum
and a lamp with 6,000 kelvins would be at the very cold white spectrum. Getting the
right colour temperature of a lamp does matter as the warm colour wavelength helps
to soften skin tones and gives a warm soft relaxed feel and at the other end of the
scale a 4,000 to 6,000 kelvin lamp colour would be used in offices or a fast food
restaurants to make you feel less comfortable and relaxed and more alert. There’s
nothing that can sour your opinion of a compact fluorescent or LED lamp like buying
a 4000K or 5000K bulb when you meant to buy a 2700K bulb, or vice-versa. When you
buy a new, energy efficient bulb, keep your application and colour scheme in mind
and make sure to buy the bulb with a colour temperature to match.

Light output ( Lumen's )

The amount of light that is produced by a lamp is called lumen's and the more lumen's
the lamp has the brighter it will be. Lumen's work in conjunction with kelvins and
watts should not be taken in isolation of each other, for example if you had a very
warm white lamp at 2,700 kelvins and it produced 300 lumen's and you then had another
lamp which was a cool white 6,000 kelvins which also produced 300 lumen's the cooler
lamp colour would always appear brighter to the naked eye than the warmer one this
is due to the receptors in the eye that react better to a white light spectrum. Another
factor on how bright a light may appear is contrast so if you shine a white 6,000
kelvin light on to a dark wall and a warm 2,700 kelvin lamp on to a white wall the
warmer lamp would appear brighter due to the contrast of the material it is focused
on. So when choosing a lamp always take in to account the area you want to illuminate
and think about Kelvins ( colour ), Lumen's ( brightness) and contrast ( colour of
area ) The more lumen's produced per watt the more energy efficient the lamp will
be, for example you can have a 25w candle lamp that produces 170 lumen's or a more
energy efficient 18w candle lamp that produces 180 lumen's so even though the wattage
is smaller the lumen's are greater which makes it use less electricity. That's what
makes LED lights so energy effective as they can produce 700 lumen's from a 5w lamp.

Light intensity or Light levels ( LUX )

Light levels are measured in something called LUX. Put simply LUX is a measurement
of light falling on a given surface area. For example an average LUX of 200 would
be needed for an outdoor tennis court for recreational purposes and a side street
walkway would have an average of 5 LUX. To calculate lux levels you need a very good
calculator or computer as there is a number of factors that need to be taken in to
account.Lux levels can be effected by a beam angle of a lamp, for example if you
had a 50w 38 degree MR16 halogen lamp at 3 mtrs from the floor and another 50w 10
degree MR16 lamp placed next to it, the one with the 10 degree beam angle would record
a higher lux level due to the concentrated light in a small area so you could drop
the 50w lamp to a 35w lamp to save energy and still achieve the desired light level.
